Caption: In a honey bee colony consisting of about 60,000 bees, only the queen (labelled with blue paint) is permitted to produce offspring, whereas her sterile daughters work around the clock to ensure the proper existence of this complex society. This image relates to an article that appeared in the March 13, 2008, issue of Science Express, published by AAAS. The study, by Dr. Robert Kucharksi and colleagues at Australian National University in Canberra, ACT, Australia, was titled "Nutritional Control of Reproductive Status in Honey Bees via DNA Methylation."
